The vehicle's TCM has apparently failed as evidenced by CEL code "U0101", low power ("limp mode"), hard shifting, no gear selection indicator, and extremely slow acceleration. Vehicle is currently available for inspection, but will be receiving a replacement TCM soon. Myself and others' safety was put at risk due to my the vehicle's inability to continue through an intersection at a reasonable rate. The problem has not been reproduced by a dealer/service center, nor has it been inspected by anyone since the incident. The aforementioned warning lamp that indicated the issue appeared upon starting the vehicle, which drove normally for the first 11 miles.

Day after driving to n a snow storm the vehicles stabilitrak and traction control light and message to service those came on the dash and a sudden lose of power. I pulled over and put it in park noticing the gear indicator on the dash was gone. I put in drive and could barely move. So I shifted to 1st gear then back to park and into drive and the light came off and it was back to normal. The next day I started the vehicle and the light was on again with the check engine light. And stuck in limp mode. There are forums I've read with thousands of people with the same problem. The vehicle is available for inspection. The safety concerns are the traction control and stabilitrak can affect the way it handles and brakes. The vehicle will be going to dealership. There where no warning light prior to. The lights and systems failed simultaneously. This vehicle only has 44000 miles on it, no rust the frame is mint. This is a very clean truck and shouldn't be having this kind of problem.

Transmission control module

The transmission control module went out on my Chevy duaramax. GM is aware of this problem in the years of 2009-2015 and has yet to fix the problem.

The Transmission Control Module failed causing the vehicle to loose power and operate only in "limp mode". General Motors does not have a replacement module available, leaving the vehicle inoperable. GM has no reliable information as to when a module will be available. I had to use a third party service to try and repair the module for a cost of over $1,200. This seems to be a common problem with the 2008-20015 GM Duramax with the Allison transmission.

When temperatures drop below 30 degrees the tire pressure warning light and the low coolant light comes on. Took to dealership and they advised that both warning lights do that below 28 degrees. This has occurred since 2013 winter. Glow plugs going out one at time gm will only replace as they go out up to 120000 not enough being done with this.
